FSK Insulation Tape

FSK insulation tape is reinforced with fiberglass scrim with a foil, scrim, and Kraft laminate backing. The reinforced aluminum foil tape offers high puncture and tear resistance, ensuring a long life and durability in various conditions and applications.

Foil-scrim-kraft (FSK) is a flame retardant, vapor-barrier, and it is one of the most commonly used facings in the insulation industry.FSK Backing Coated with Synthetic Rubber Resin Adhesive.The combined backing properties result in a strong tape that provides a barrier against vapor.It can also be used for patching rips and tears in foil-facing insulation and can be used with fiberglass duct wrap for added strength.

FSK Tape Applications:

FSK insulation tape is used for sealing and patching FSK ductwork and insulation and provides a finished look for exposed HVAC systems.FSK is the basic insulation facing.

FSK Tape Features:

Scrim layer bends with the primary facing providing integrity to the insulation and a strong, finished, appearance.
Release liner provides easy removal for efficient application on the job site.
High-tack synthetic rubber adhesive forms an instant bond.
Moisture-, mold-, and UV-resistant design.
